Poly(2-fluoro-1,4-phenylenevinylene), PFPV, and its copolymers have been synthesized via water soluble precursor route and their electrical and optical propreties were measured. It seems that electron-withdrawing fluorine substituent on phenylene ring increases the band-gap of PFPV and it affects electrical and optical properties. The conductivity values of FeCl-doped drawn polymer films ranged from 10 to 10 Scm depending on their composition, and were 10 times larger than those of undrawn ones. The χ value for undrawn PFPV, using THG technique at 1907nm fundamental wavelength, was 4.76x10 esu. [ABSTRACT FROM AUTHOR] |
